Nasal reconstruction in pediatric patient is very challenging and it requires consideration of later nasal development. Herein, we introduce an innovative preauricular free flap pedicled with retrograde vascular (PFFPRV) for pediatric nasal reconstruction. In this PFFPRV technique, the retrograde superficial temporal vessels were used as the flap pedicle. The lateral alar artery and angular vein were used as vessels of the nasal recipient zone. The flap vessels were anastomosed directly to the recipient area vessels without additional vessel transplantation. Eight pediatric patients with nasal defects underwent this operation. All patients were followed up for more than 2 years. Patients' medical history data were retrospectively analyzed. Preoperative and postoperative facial photos were compared and analyzed. The satisfaction of patient's parents with the aesthetic results was assessed. All patients were successfully operated without intraoperative complications. None of the procedures required additional blood vessel grafts. One patient developed a vascular crisis the next day after the surgery and underwent vascular exploration operation. The free flaps of all patients survived without wound infection or necrosis. The color difference of flap gradually became unobvious. The transplanted flap did not show obvious contracture or retraction, and the nose was symmetrical and developed well. The parents of all patients were satisfied with the surgical results. We think this PFFPRV technique can be a reasonable alternative strategy for reconstruction of pediatric nasal defect, with no adverse effect on nasal development and no need of vascular transplantation.
